Thank you, gentlemen, for your compliments about my work on altar cards here at Myriad Creative Concepts. If there are materials that you need but cannot find,
let me know because I will bend over backwards to design them for you. Right now, I am working on three special request projects: a Latin Novus Ordo Mass Altar
Card, Dominican Rite Altar Cards, and travel sized altar cards that will fit in a briefcase. Again, thank you for your kind words.

There are two views of altar cards. one is that they're necessary nay, indispensible. The other, esposed by the late Percy Dearmer, is that they're unnecessary - and probably don't have authority in the English Church. I'm not violently 'anti' but I think it's a better practice to keep your eyes on the text in the Missal when celebrating.

The guidance, and law in the Roman Church prior to Vatican II was to trust the missal and not your memory. The altar cards (or charts in some places) were an extention of the Missal, and were intended to aid the memory, and not to replace the missal. Most of the prayers that one sees printed on them are when the priest is oriented in a position that would make using the text directly from the missal a bit of a strain. As an example, while it was (and when there is a proper Last Gospel) is the norm to move the missal to the Gospel side, it is no longer the norm.

My rule of thumb is that if the altar is fairly long you need altar cards for the Anglican/American/English Missal. However, as the altar here is relatively small and I don't say the Last Gospel so I can celebrate without cards. For a straight BCP Mass Altar cards are unneccessary, though I do have the Sarum offertory prayers on a postcard paper-clipped in at the appropriate spot, but that's because I feel it is odd not to have some sort of private prayer for the celebrant at the offertory.
